<h3 id="rationale">Rationale:</h3>
<p>By default, <code>xargs</code> interprets spaces and quotes in an
unsafe and unexpected way. Whenever it's used, it should be used with
<code>-0</code> or <code>--null</code> to split on <code>\0</code>
bytes, and <code>find</code> should be made to output <code>\0</code>
separated filenames.</p>
<p>POSIX does not require find or xargs to support null terminators, so
you can also use <code>find -exec +</code>.</p>
<h3 id="exceptions">Exceptions</h3>
<p>None.</p>
